Incident #20 Sighting Report — Xenia, Ohio, 20 October 1947

This document details Incident #20, a UAP sighting that occurred in Xenia, Ohio, on October 20, 1947, at 1600 hours. The report, associated with Project Grudge, documents the observation of a single, round, silver object approximately 12 inches in diameter. The object was observed moving on a straight course toward the southwest at an estimated altitude of 1000 to 1500 feet. The witness, identified as a female civilian, reported that the object moved at a fast speed and made no sound. The report includes an evaluation by Dr. Hynek, which concludes that the available information is insufficient to determine an astronomical origin. The investigators noted that while a meteoric explanation could not be ruled out, the lack of data concerning the object's trail, the duration of the sighting, and the distance from the observer made a definitive conclusion impossible. The report further notes that it is highly improbable the object was a daylight, slow-moving bolide based on the limited information provided. The document also mentions that the observer reported the presence of two witnesses.
